2. Description of Related Art

In recent years, with the popularity of mobile products with camerafunctionalities, a demand for optical system is increasing. Aphotosensitive sensor of a conventional optical system is typically aCCD (Charge-Coupled Device) or a CMOS (ComplementaryMetal-Oxide-Semiconductor) sensor. As advanced semiconductormanufacturing technologies have allowed a pixel size of sensors to bereduced and the optical systems have gradually evolved toward a field ofhigher megapixels, there is an increasing demand for better imagequality.

A conventional optical system employed in a portable electronic product,as shown in U.S. Pat. No. 7,869,142, mainly adopts a structure of fourlens elements. Due to the popularity of mobile products with high-endspecifications, such as smart phones and PDAs (Personal DigitalAssistants), requirements of higher megapixels and better image qualityhave increased rapidly. However, the conventional optical systems cannotsatisfy the requirements of high-end optical systems with camerafunctionalities.

A conventional optical image lens assembly with many lens elements isusually too bulky to have its size being miniaturized; therefore, it isnot applicable to portable electronic products with a compact size. Anoptical image lens assembly with five lens elements, such as “ImagingLens Assembly” disclosed in U.S. Pat. No. 8,000,030, lacks good abilityto correct high order aberrations and off-axis aberrations. Moreover,the space arrangement, the distribution of refractive power and thedesign of lens surface are not favorable to have its total track oflength being effectively shortened thereof and it is thereby not easy tohave a compact size with good image quality.

DETAILED DESCRIPTION

An optical image capturing system in order from an object side to animage side, includes a first lens element, a second lens element, athird lens element, a fourth lens element, a fifth lens element, a sixthlens element and a seventh lens element. The optical image capturingsystem further includes an image sensor disposed on an image plane ofthe optical image capturing system.

Each of the first lens element, the second lens element, the third lenselement, the fourth lens element, the fifth lens element, the sixth lenselement and the seventh lens element is a single and non-cemented lenselement. That is, any two lens elements adjacent to each other are notcemented (such as the image-side surface of the first lens element andan object-side surface of the second lens element), and there is an airspace between the two lens elements. That is, an air distance betweentwo adjacent surfaces of any two adjacent lens elements. Since themanufacturing process of the cemented lenses is more complex than thenon-cemented lenses. In particular, a second surface of one lens and afirst surface of the following lens need to have accurate curvature toensure these two lens elements will be highly cemented. However, duringthe cementing process, those two lens elements might not be highlycemented due to displacement and it is thereby not favorable for theimage quality of the optical image capturing system. Therefore, theoptical image capturing system of the present disclosure provides sevensingle and non-cemented lens elements for improving upon the problemgenerated by the cemented lens elements.

The first lens element with positive refractive power has a convexobject-side surface and a concave image-side surface, so that a totaltrack length of the optical image capturing system can be reduced byadjusting the positive refractive power of the first lens element.

The second lens element has a convex object-side surface and a concaveimage-side surface so that an astigmatic of the optical image capturingsystem can be corrected.

At least one of an object-side surface and an image-side surface offourth lens element can include at least one inflection point,respectively.

The fifth lens element with negative refractive power can correct anaberration of the optical image capturing system so as to improve imagequality. The fifth lens element can have a concave object-side surfaceand a convex image-side surface, so that the fifth lens element caneffectively correct the astigmatism of the optical image capturingsystem.

The sixth lens element with positive refractive power has an object-sidesurface and an image-side surface which are both convex, so that an highorder aberration of the optical image capturing system can be correctedso as to enhance a resolving power of the optical image capturing systemfor better image quality. Furthermore, the object-side surface of thesixth lens element changes from convex at a paraxial region to concaveat a peripheral region so as to maintain a relative illumination of theperiphery of images.

The seventh lens element with negative refractive power has anobject-side surface and an image-side surface which are both concave, sothat a principal point of the optical image capturing system can bepositioned away from the image plane for reducing a back focal lengththereof so as to further reduce the total track length of the opticalimage capturing system and maintain a compact size thereof. Moreover,the image-side surface of the seventh lens element changes from concaveat a paraxial region to convex at a peripheral region, and the seventhlens element has at least one inflection point formed on the image-sidesurface thereof. Therefore, an incident angle of an off-axis field ontothe image sensor can be effectively minimized, and preferably,aberrations of the off-axis field can be corrected.

When a curvature radius of the object-side surface of the seventh lenselement is R13, and a curvature radius of the image-side surface of theseventh lens element is R14, the following relationship is satisfied:−5.0<R14/R13<1.0.

By such an arrangement, the configuration of the surface curvature ofthe seventh lens element is favorable for the disposition of the otherlens elements, the arrangement of the aspheric surface of the other lenselements and the arrangement of the inflection point to correct the highorder aberration and the off-axis aberrations, for example, the comaticaberration and the astigmatism, and to reduce the angle at which theincident light projects onto the image sensor from the off-axis fieldunder a certain total track length and to realize an optical imagecapturing system with a better image quality and a compact size.

Preferably, the optical image capturing system further satisfies thefollowing relationship:−2.0<R14/R13<0.5.

When a focal length of the optical image capturing system is f, a focallength of the sixth lens element is f6, and a focal length of theseventh lens element is f7, the following relationship is satisfied:1.8<|f/f6|+|f/f7|<6.0.

By properly arranging the focal lengths of the sixth lens element andthe seven lens element so as to form a positive-negative telephotostructure, the total track length of the optical image capturing systemcan be effectively reduced. Preferably, the optical image capturingsystem further satisfies the following relationship:2.3<|f/f6|+|f/f7|<5.0.

When a distance in parallel with an optical axis from a maximumeffective diameter position on the image-side surface of the fifth lenselement to an axial vertex on the image-side surface of the fifth lenselement is SAG52, and a central thickness of the fifth lens element isCT5, the following relationship is satisfied:−0.7 mm<SAG52+CT5<−0.1 mm.

Accordingly, it is favorable for manufacturing and assembling the lenselements by arranging a proper surface curvature of the image-sidesurface of the fifth lens element and a proper thickness of the fifthlens element.

When an Abbe number of the first lens element is V1, and an Abbe numberof the second lens element is V2, the following relationship issatisfied:28<V1−V2<42.

Accordingly, a chromatic aberration of the optical image capturingsystem can be corrected.

When the focal length of the optical image capturing system is f, and anaxial distance from the object-side surface of the first lens element tothe image-side surface of the seventh lens element is Td, the followingrelationship is satisfied:0.50<Td/f<1.35.

Therefore, the total track length of the optical image capturing systemcan be effectively reduced so as to keep the optical image capturingsystem compact.

Preferably, the optical image capturing system further satisfies thefollowing relationship:0.80<Td/f<1.25.

When the focal length of the optical image capturing system is f, afocal length of the third lens element is f3, and a focal length of thefourth lens element is f4, the following relationship is satisfied:|f/f3|+|f/f4|<1.0.

Therefore, the focal lengths of the third lens element and the fourthlens element are favorable for reducing the sensitivity of the opticalimage capturing system.

When the focal length of the optical image capturing system is f, andthe focal length of the seventh lens element is f7, the followingrelationship is satisfied:−3.0<f/f7<−1.3.

Consequently, the refractive power of the seventh lens element will befavorable for further reducing the back focal length of the opticalimage capturing system so as to reduce the total track length of theoptical image capturing system.

When a minimum central thickness of a lens element among all lenselements of the optical image capturing system is CTmin, the followingrelationship is satisfied:0.10 mm<CTmin<0.30 mm.

Therefore, by adjusting the thickness of the lens elements, it isfavorable for manufacturing the lens elements, and preventing theover-thin lens elements from being formed abnormally so as to increasethe yield rate of the lens elements.

When the focal length of the optical image capturing system is f, and avertical distance from a critical point on the image-side surface of theseventh lens element to an axial vertex on the image-side surface of theseventh lens element is Yc72, the following relationship is satisfied:0.1<Yc72/f<0.9.

Accordingly, the angle at which the incident light projects onto theimage sensor from the off-axis field can be effectively reduced toimprove the image quality.

When a maximal field of view of the optical image capturing system isFOV, the following relationship is satisfied:72 degrees<FOV<95 degrees.

Accordingly, a larger field of view can be provided so as to obtain therequired image scope and to avoid the image from distortion.

When the curvature radius of the image-side surface of the seventh lenselement is R14, and the focal length of the optical image capturingsystem is f, and the following relationship is satisfied:0.1<R14/f<1.0.

Therefore, the curvature radius of the image-side surface of the seventhlens element will be favorable for the principal point of the opticalimage capturing system being positioned away from the image plane sothat the back focal length thereof can be reduced and the compact sizethereof can be maintained.

When a maximum image height of the optical image capturing system isImgH, and an axial distance between the object-side surface of the firstlens element and the image plane is TTL, the following relationship issatisfied:1.00<TTL/ImgH<1.70.

Thus, the total track length of the optical image capturing system canbe reduced so as to maintain the compact size thereof, and suitable forapplying to the compact portable electronic products.

In the optical image capturing system of the disclosure, the lenselements can be made of plastic or glass material. When the lenselements are made of glass material, the distribution of the refractivepower of the optical image capturing system can be more flexible todesign. When the lens elements are made of plastic material, themanufacturing cost thereof can be decreased.

Furthermore, surfaces of each lens element can be arranged to beaspheric, because the aspheric surface of the lens element is easy toform a shape other than spherical surface so as to have morecontrollable variables for eliminating the aberration thereof, and tofurther decrease the required number of the lens elements. Thus, thetotal track length of the optical image capturing system can beeffectively reduced.

In the optical image capturing system of the disclosure, each of anobject-side surface and an image-side surface of every lens element hasa paraxial region and a peripheral region. The paraxial region refers tothe region of the surface where light rays travel dose to an opticalaxis and the peripheral region refers to the region of the surface wherelight rays travel away from the optical axis. Particularly, when a lenselement has a convex surface, it indicates that the paraxial region ofthe surface is convex; and when the lens element has a concave surface,it indicates that the paraxial region of the surface is concave.

According to the optical image capturing system of the presentdisclosure, a critical point is a non-axial point of the lens surfacewhere its tangent is perpendicular to the optical axis.

In the optical image capturing system of the disclosure, the opticalimage capturing system can include at least one stop, such as anaperture stop, a glare stop or a field stop. Said glare stop or saidfield stop is for eliminating the stray light and thereby improving theimage resolution thereof.

In the present optical image capturing system, an aperture stop can beconfigured as a front stop or a middle stop. A front stop disposedbetween an object and a first lens element can provide a longer distancebetween an exit pupil of the system and an image plane and whichimproves the image-sensing efficiency of an image sensor. A middle stopdisposed between the first lens element and an image plane is favorablefor enlarging the field of view of the system and thereby provides awider field of view for the same.

The optical image capturing system do not only equip with superioraberration correction functionality but also equip with superior imagequality that can be applied to many electronic image systems, such asthree-dimensional image capturing systems, digital cameras, portabledevices or digital tablets.
